## Long description

SMARTMAX Cotman Serie 666 flat 3/8 is a flat-shaped artist brush designed for watercolor, ink and other fluid media. The medium-narrow 3/8 width produces controlled linear strokes and measured washes, while the flat profile enables broad marks, crisp edges and precise application for illustration, sketching and detailed work.
Advantages
The synthetic Cotman filament holds and releases pigment evenly, providing consistent flow for washes and ink lines. The flat shape maintains a straight edge for sharp contours and can also be turned on its side for broader coverage. A balanced wooden handle offers comfortable control during extended sessions, and the ferrule secures the head to minimize wobble and maintain shape.
Suitable for
Watercolor washes and layering
Ink drawing and wash techniques
Illustration, architectural lines and edges
Sketching, blocking in color and backgrounds
Key specifications
Brush shape: flat
Size: 3/8 (medium-narrow)
Filament: synthetic Cotman-style
Handle type: wooden, short or medium length for control
Compatibility: designed for water-based media such as watercolor and ink
How to use
Wet the brush and load it with diluted watercolor or ink to achieve the desired flow. Use the flat edge for precise strokes and crisp lines, rotate the brush on its side for broader washes, and adjust pressure to vary line width. Rinse the brush frequently when changing colors and reshape the tip gently before setting it to dry to preserve the flat profile and filament alignment.
Usage recommendations
Clean with lukewarm water and mild soap after each use, avoid soaking the wooden handle for prolonged periods, and store horizontally or tip-up to retain shape. For best results, use with student and artist-grade water-based pigments and avoid aggressive solvents that can damage synthetic filaments or the handle.
